At line 5 ff. the poet bids his addressee circulate along the benches of a ship and drink deeply: he gives as a reason the company's inability to remain sober in this spell of guard-duty.
Should we conclude that Archilochus sang this song for the first time while on guard by a beached ship? If so, I am tempted to suggest that the reason we have no more of the song is that the singer's throat was cut by a Thracian guerrilla: for real guard-duty is not effective if punctuated by drunken song.

(To be fair, there is no reason why soldiers on watch wouldn't *sing* songs about being drunk while on watch, even if they weren't actually drinking, is there?)
